Deploying a Web Application on AWS

AWS Service	Deployment Type	Main Use Case	Server Management	Scalability	Notes
Elastic Beanstalk	PaaS (Platform as a Service)	Quickly deploy web applications (Node.js, Python, Java, etc.)	Automated	Automatic	Very easy to use, but less flexible than ECS/EKS
Amazon ECS	Containers (Docker)	Run Docker containers on AWS	Self-managed or managed (Fargate)	High	Integrated with ECR and CloudWatch. Uses container clusters
AWS Fargate	Serverless containers	Run containers without managing infrastructure	Nothing to manage	Automatic	Simplified version of ECS, ideal for microservices
Amazon EKS	Kubernetes (advanced orchestration)	Deploy complex containerized applications	You configure it yourself	Very high	More complex, recommended for large Kubernetes architectures
Amazon EC2	Virtual machine	Full control over the environment, manual installation	Managed manually	Manual	Flexible but requires more administration
AWS Lambda	Serverless (Function-as-a-Service)	Run backend functions without servers (APIs, event processing)	Nothing to manage	Automatic	Well suited for simple microservices or stateless APIs
Amazon S3 + CloudFront	Static hosting + CDN	Host static websites (HTML, CSS, JS)	None	Automatic (CDN)	Ideal for SPA frontends (React, Angular…)
API Gateway + Lambda	Serverless backend API	Create REST or HTTP APIs without servers	None	Automatic	Perfect with Lambda for building a complete serverless backend
CloudFormation	Infrastructure as Code	Automate the deployment of complete infrastructures	Describes the infrastructure in YAML	Depends on the service used	Used to automate any deployment, not to host an application directly

Recommendations based on your needs:

• Simple or traditional web application: Elastic Beanstalk or ECS Fargate.
• Containerized application/microservices: ECS (or EKS if you’re comfortable with Kubernetes).
• Static application (frontend only): S3 + CloudFront.
• Backend application with event-driven logic: API Gateway + Lambda.
• Controlled, manual deployment: EC2.
• Automated deployment: CloudFormation or CDK (Infrastructure as Code).
